net: ethernet: cortina: Count RX drops once per frame
The absence of a partial skb means either that the driver is not
assembling a frame or that the current frame was already dropped.
Consequently, repeated descriptor errors can increment rx_dropped more
than once, while an orphaned descriptor chain can reach EOF without being
counted at all.
Track the dropping state across NAPI polls. Clear it at frame boundaries
and route mapping failures and orphaned continuations through the common
drop path so each discarded frame is counted exactly once.
